1Hardware Replacement Guide

Overview

This guide is intended to be used by customers who are replacing Customer Replaceable Units (CRUs) as well as trained service personnel who are replacing Field Replaceable Units (FRUs). In this guide, CRUs and FRUs will often be referred to as parts.

Note: Trained service personnel should refer to the Hardware Maintenance Manual (HMM) for parts ordering information.

This guide does not include procedures for all parts. It is expected that cables, switches, and certain mechanical parts can be replaced by trained service personnel without the need for step-by-step procedures.

Note: Use only parts provided by Lenovo.

The description of the TV-Tuner card in this manual applies only to those models that have the TV-Tuner card installed. It does not apply to those models that do not have the TV-Tuner card installed.

This guide contains procedures for replacing the following parts:

Memorymodules

Harddiskdrive

Opticaldrive

Keyboard,mouse(wired)

Powercord

Safety information for replacing CRUs

Handling static-sensitive devices

Static electricity, although harmless to you, can seriously damage computer components.

When you are replacing a part, do not open the anti-static package containing the new part until the defective part has been removed from the computer and you are ready to install the new part.

When you handle parts and other computer components, take these precautions to avoid static-electricity damage:
